Dos & Dont's - Penflex

Do…

follow any printed instructions included with the flexible connector.
follow industry–recommended practices and use care in handling and installing flexible connector.
install flexible connectors so that the bend is as close to the center of the connector as possible.
observe the minimum bend radius as specified by the connector manufacturer.
trial-fit threaded connections by hand, unmake and then make permanent.
use a flexible connector of proper length to suit the installation.
only wrench on the fitting hex flats as provided.
design the installation to allow for ground movement after installation, such as settling or frost heave.
install the proper length connector to allow a 2” straight run of hose at each end fitting.
use pipe wrenches on both mating hexes to avoid twisting the hose.
keep hose free from all objects and debris.
handle and store connectors carefully prior to installation.
check for leaks before covering the installation.
install in such a manner that the connector can be removed.
make sure the pressure rating of connector is not exceeded.

Don’t…

apply a wrench to a hose, collar or assembly.
twist hose assemblies during installation or when aligning the bolt holes in a flange or when making up pipe threads.
“pre–flex” a flexible connector to limber it up. Over–bending could cause damage and result in leakage.
over–bend a flexible connector. A 45°–90° bend should be sufficient to install any flexible connector.
install a flexible connector with the bend next to the end fittings. This could cause damage and result in leakage.
lay the flexible connector on rocks or objects which could puncture the hose and cause leakage.
attempt to stretch or compress a flexible connector to fit an installation.
restrict flexibility by allowing connector to come into contact with other components or equipment during installation.
